cold crank

works good, still seems to have trouble starting on COLD days. turns over fine, just not as good as a HARD kick. Never need charged. Very good battery, I was just expecting it to be 5 times the cranking power. Bottom line, always stays charged , even after sitting a long time. BAD-- it takes a special charger(not included) . I never bought one because it stays charged.

Good battery

Factory replacement

OEM Battery Replacement

I installed this battery on a 2001 Aprilia RSV1000. Battery matches the OEM unit exactly. I've never activated a battery like this before by pouring the acid, but the instructions make it totally easy. The system is almost foolproof so don't let that put you off. The benefit is that a dry battery has a significantly longer shelf life. Once I pour the acid and charge the battery for the first time (I used a Battery Tender Jr) the battery has not lost any of its charging ability due to sitting. Highly recommended for OEM replacement.
